Descripción

area:pricing difficulty:intermediate epic:data-quality help wanted points:150 Stellar Wave
Background

Lens recommends routes and predicts slippage. It never looks at what the chain did afterwards, so there is no evidence the predictions are accurate — and no way to notice when they stop being.

What to build
  • Sample executed trades for pairs Lens quoted and compare realised price against the prediction.
  • A periodic accuracy report per venue and pair.
  • Expose it, because publishing your own error bars is the most credible thing a price API can do.
Acceptance criteria
  • Predictions are stored and compared against realised trades
  • Accuracy is reported per venue and pair
  • The report is queryable through the API
  • A test covers a predicted and a realised trade

Repo: Divinity-Labs/Lens. Node + Fastify + Prisma + Postgres. Tests are vitest (npm test), not jest — jest against this repo fails every file and tells you nothing.

?network= is not optional on a new route. Every row carries a network and the indexes lead with it. Read req.network ?? activeNetwork, filter on it, echo it in the response, and declare the parameter in openapi.yaml. tests/openapi.test.ts boots the server and fails if a registered route is missing from the spec.

A number without provenance is not an answer. Every figure this batch adds must carry what it was computed from: which venues, how many samples, how fresh. The point of Lens is that its numbers can be checked.

Never elide a contract id or an issuer. Take addresses from the protocol's own documentation and write them whole. A sibling repo's issue wrote CD2W5LUR…XZ4L and five contributors invented plausible contract ids to fill the gap.

Say when you cannot answer. An asset with no liquidity, a pair with one venue, a window with a gap — each has an honest answer that is not zero and not a 500. Zero is a number people act on.
